AI Technical Summary
During the construction of continuous beam hanging baskets, the PVC pipe hole structure is prone to deflection and floating, causing the bottom of the reserved hole to be covered by concrete, which affects the installation of fine rolled threaded steel.
The pre-drilling device, consisting of steel plate one and steel plate two, includes a pre-drilling mechanism, a lifting mechanism, and a fixing mechanism. It utilizes internal threads, external threads, retaining rings, steel pipes, and elastic components to ensure that the PVC pipe does not deviate or float during concrete pouring.
This effectively prevents the reserved holes from being covered by concrete, ensures unobstructed passage, and improves the installation stability and construction safety of precision-rolled threaded steel bars.
